问题如下:
Which of the following is the best reason for an investor to be concerned with thecomposition of a portfolio?
选项:
A. Risk reduction.
B. Downside risk protection.
C. Avoidance of investment disasters.
解释:
A is correct.
Combining assets into a portfolio should reduce the portfolio’s volatility. The portfolio approach does not necessarily provide downside protection or guarantee that the portfolio always will avoid losses.
这道题是在讲义的哪里呢?risk reduction是指风险下跌,为什么风险下跌还会让投资者关心组合的构成呢?? 另外,downside risk protection是对风险下跌的保护??怎么翻译,怎么理解这个选项?
